1. LS204Module IV – Part 2 Tools and Techniques Workbook - Coach

2. Module IV – Tools and Techniques • Welcome to Module IV: • Chapter 4 – Code and Regulations • Chapter 5 – The Proposal • Practice Activities: • Two Exercises • Online Quiz

3. Learning Objectives • Understand a verbally express the topics covered in ASHRAE 90.1 – 2010, and be able to reference it in the “read only” inline version of the Standard • Understand the outline and be able to craft a lighting proposal for their live Practicum.

4. How Does This Apply to My Work? • ASHRAE 90.1 – 2010 is a challenging Code to master. Becoming familiar with the topics it covers and where to look for the specific within the Standard will help you elevate your game above the competition. • Being able to take what you learn in the field and put it together into a viable proposal requires focus and attention to detail. The benefit – you own the information and can easily and fluently explain it to your customer.

5. ASRHAE 90.1-2010 • ASRHAE 90.1-2010: mandatory requirements: • Area controls • Automatic lighting shutoff • Bi-level lighting • Daylight harvesting • Exterior lighting control • Parking garage lighting control • Stairwell lighting control • Designer must ensure that all lighting controls are functionally tested.

6. ASHRAE/IES 90.1-2010 DOE Ruling • The U.S. Department of Energy (DOE) ruling: • All states to file a plan to update the their commercial building codes regarding energy efficiency need to meet or exceed ASHRAE 90.1-2010 by Oct. 18, 2013. • Map shows States that have adopted • Other States filed for extensions.

The User’s Guide is very helpful.

9. Comparing 2010 – earlier versions • http://lightingcontrolsassociation.org/ashrae-releases-90-1-2010-part-1-design-scope-administrative-requirements/ • http://lightingcontrolsassociation.org/ashrae-releases-90-1-2010-part-2-lighting-controls/ The following provide links to two articles published by the Lighting Controls Association. They explain ASHRAE 90.1 and compare it to previous versions. The table allows you to compare the Lighting Power Density of 2010 with previous versions of the Standard.

12. Using This Summary • The following outline of the Standard is intended only to highlight what is discussed in each area of the Standard so that you can either look it up in full detail in the Read Only online version, or so that you can review it in the hard copy of the Standard, or use the User’s Guide to clarify the meaning of the Standard.

13. Compliance Required When… • Alteration of 10% or more of the connected load in a given area enclosed by floor to ceiling partitions. • Example: You have a four story office building. You renovate one floor. Affecting 25% of the connected load. • Compliance with ASHRAE 90.1 2010 required? • Yes, but only for the floor under renovation. • Source: ASHRAE 90.1 – 2010 User’s Guide
